Texas Instruments Semiconductor's F2802x Piccolo family of MCUs uses the C28x core, a high-efficiency 32-bit MCU that operates frequently up to 60Mz, and integrates a wide range of control peripherals with a small pin count. The internal voltage regulator allows it to be used. Single-supply operation at 3.3V. The analog comparator uses a 10-bit reference to directly control the PWM output. The ADC converter converts the 0V to 3.3V analog to a digital signal. This article describes the main features of the F2802x Piccolo family of MCUs, block diagrams, and digital motors. The main features of the control and PFC kit, the complete permanent magnet motor control system and the block diagram of the motor control and PFC development kit.

The F2802x Piccolo family of microcontrollers provides the power of the C28x core coupled with highly integrated control peripherals in low pin-count devices. This family is code compatible with previous C28-based code, as well as providing a high level of analog integration.
Enhancements have been made to the HRPWM module to allow for dual-edge control (frequency modulation). Analog comparators with internal 10-bit references have been added and can be routed directly to control the PWM The ADC converts from 0 to 3.3-V fixed full scale range and supports ratio-metric VREFHI/VREFLO references. The interface has been optimized for with low overhead/latency.

Additionally, systems can calibrate themselves, thus eliminate the need to schedule regular, manual maintenance.
Today's microcontrollers (MCUs) bring even greater precision, power efficiency and reduced cost to a wide range of applications, including:
White goods and appliances with blowers and compressors such washers and refrigerators
HVAC (Heating, Ventilation and Air Conditioning) systems
Industrial servo drives used for motion control, power supply inverters and robotics
Automotive control systems, including power steering, anti-lock brakes and suspension controls Creating robust digitally controlled systems has never been easier. TI's Motor Control and PFC Developer's Kit as well as the Dual-Motor Control and PFC Developer's Kit are based on Piccolo MCUs to Give developers a platform that accelerates development and troubleshooting of motor control systems. The intuitive kits even teach developers unfamiliar with PFC how to merge PFC with motor control applications of all types.
The Motor Control and PFC kits provide direct access to all of the enhancements and features of the Piccolo architecture. Extensive software libraries and thorough documentation lead developers through the process of creating a complete motor control system utilizing real-time algorithms. From the baseline, they are then able to bring in advanced algorithms to trade-off the remaining processing capacity for greater accuracy, better performance, higher power efficiency, control of multiple motors and a myriad of other options. In this way, developers can architect systems specifically optimized for their application constraints and requirements.

Classical Crystal Floor Light is a kind of floor lamp with Metal and crystal for main material. Floor lamps are generally placed in the rest area of the living room, and sofa, coffee table with, on the one hand to meet the needs of the region lighting, on the one hand the formation of a specific atmosphere. Usually, the floor lamp should not be placed in the area of tall furniture or hinder the activities of the area. These type light used E14/E27/E12/B22 lamp holder. There are many different patterns and designs for customer to choose. We can make light according to customers' requirments.
